Is an increase in premature beats after exercise harmful?

The increase in premature beats after exercise is generally harmless for healthy people, but should be noted for patients with cardiovascular disease.
For healthy people, a small number of premature heart beats after sitting and exercising is a normal physiological phenomenon, which is generally harmless and no need to be overly nervous. It is recommended to have a regular routine, relax your body and mind, stay up late and drink less strong tea and coffee. If there is an increase in the number of premature beats after exercise, it should be noted and it is recommended to consult a doctor to find out the cause.
If you suffer from underlying cardiovascular diseases (e.g. coronary heart disease, arrhythmia), you need to pay attention. For people with coronary heart disease, premature beats after exercise may indicate myocardial ischemia; for patients with arrhythmia (such as pre-excitation syndrome), premature beats may induce tachycardia or even sudden death, which is dangerous.
Therefore, if there is a frequent increase in premature beats after exercise or palpitations, it is recommended to consult a doctor as soon as possible to find out the cause and get timely treatment.
